Dimension；Guan Liang is obtained by pultrusion after carbon fiber prepreg winding or carbon fibre initial rinse liquid-state epoxy resin；
Step 2: joint and Guan Liang are fixed in frock in order using assembly tool, and connection in need
Joint boss and pipe beam inwall smearing structure glue, pipe beam inwall smearing depth boss corresponding with joint is consistent, need to smear uniformly；
Further, before step 2, pipe beam inwall and joint protuberance is cleaned with acetone, reaches the purpose of cleaning, goes
Except the releasing agent and grease of surface attachment.
Further, be integrally formed logical line path during injection, the routing path after connecting tube beam can with Guan Liang
Cavity connects, for arranging brake cable, electric wire, control line or signal wire.
Further, before washing, pipe beam inwall and joint protuberance are roughened, improve gemel connection
Effect.
More particularly, glue thickness is 0.1-0.2mm, quickly inserts composite material tube on pallet boss.
Advantage is caused by the technology of the present invention：1. pallet and pipe fitting can the quick manufactures of low cost；2. plug-in position
There is provided 30-40mm bonding boss, using the teaching of the invention it is possible to provide enough adhesive strengths；3. being bonded the taper that boss carries 1-5 °, can make
Structure glue is uniformly spread out, and facilitates joint to be positioned with pipe；4. joint versatility and interchangeability are stronger, according to wanting for different size vehicle frames
Ask, can be arranged in pairs or groups out various sizes of vehicle frame specification, and condition is provided for vehicle frame variation, overcome existing vehicle frame single uncurrent
Shortcoming；5. whole vehicle frame is decomposed into independent several parts, it can individually be processed, lowered molding difficulty by specialized factory, be advantageous to carry
High finished product rate；6. pallet employs structure glue bonding forming with pipe, static strength and fatigue behaviour are relatively reliable；7. vehicle frame group
Dress process has corrected that corresponding size, without also needing to correct size as the traditional handicraft later stage.
