The present invention relates to the insulation of a kind of wooden base, energy-absorbing multilamellar truss core structure and preparation method thereof.This structure is made up of top panel (1), upper resin bed (2), foam heat-insulation layer (3), lower resin bed (4), lower panel (5) and sandwich layer rod member (6).Preparation method specifically comprises the following steps that one, prepares resin energy-absorbing plate；Two, foam heat-insulating board is prepared；Three, truss core structural core layer is prepared；Four, truss core structure is prepared.The present invention solves wood-based plate and utilizes, as wooden engineering material, the problem that insufficient strength, performance are single, improves existing wooden basic point battle array sandwich structure panel and sandwich layer cutting performance.
Description
Technical field
The invention belongs to heterogeneous material compound design field, relate to the insulation of a kind of wooden base, energy-absorbing multilamellar truss core knot
The preparation method of structure.
Background technology
Truss core structure has that light weight is high-strength, designability and multi-functional potentiality, with metal, resin composite materials
Prepare truss core structural research for matrix relatively broad, but prepare Multifunctional dot-matrix sandwich structure with wooden base and make it at wood
It is less that matter engineering material field carries out applied research.
In the case of natural forest resource and big-diameter wood reduce day by day, if utilizing, material is the softest, intensity is relatively low
Artificial fast-growing woods and the wood-based plate utilizing wood machining residues to produce prepare wooden base Multifunctional dot-matrix sandwich structure, it is achieved
It, in the application in Wood construction field, for alleviating China's timber resource shortage, improves timber utilization rate aspect significant.
Summary of the invention
The present invention is to solve that wood-based plate is as wooden engineering material application insufficient strength and truss core structural panel
The problem not enough with the bonding strength of sandwich layer rod member, proposes the insulation of a kind of matter base, the preparation side of energy-absorbing multilamellar truss core structure
Method.
A kind of wooden base insulation, energy-absorbing multilamellar truss core structure, specifically by top panel (1), upper resin bed (2), foam
Heat-insulation layer (3), lower resin bed (4), lower panel (5) and sandwich layer rod member (6) composition.
The insulation of a kind of wooden base, the preparation method of energy-absorbing multilamellar truss core structure, specifically sequentially include the following steps:
One, the preferable resin of energy absorption performance is selected to prepare resin energy-absorbing plate by mould molding.
Two, by the way of machine drilling, foam heat-insulating board is holed, foam heat-insulating board aperture size and sandwich layer bar
Part, resin bed aperture size are consistent.
Three, the resin plate that step one obtained, sandwich layer rod member, foam heat-insulating board assemble, and prepare truss core structure
Sandwich layer.
Four, truss core structural core layer step 3 prepared carries out bonding with top panel, lower panel by adhesive.
Wherein, it is the impact energy absorption ability in order to improve wooden basic point battle array sandwich structure that step one prepares resin plate, step
Foam heat-insulating board in three sandwich layers is to improve the heat-insulating property of truss core structure and fixing sandwich layer rod member, improves
Its anti-shear ability.The wooden basic point battle array sandwich structure preparation method that the present invention uses be good characteristic based on wood materials with
And the structural advantage of truss core structure, utilize the preferable energy absorption performance of resin material and the heat-insulating property of foamed materials, system
Standby a kind of wooden base insulation, energy-absorbing multilamellar truss core structure, that has widened wooden resource utilizes scope, improves wooden resource
Comprehensive utilization ratio.
The invention has the beneficial effects as follows:
1, a kind of wooden base of present invention insulation, energy-absorbing multilamellar truss core structure are by artificial fast-growing woods poor for material and power
The wood-based plate learning intensity relatively low is applied in wooden engineering material, and that has widened wooden resource utilizes scope, improves wooden resource
Utilization rate.2, the effective energy absorption performance of resin bed extends the time of structural failure, improves it and apply as wooden engineering material
Safety coefficient.3, core structure improves right cylinder type truss core structural plane core shear strength.
