The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, present embodiment extremely-low density light material laminate is formed by 5 layers of oxford lightweight prepreg 1 laminating hot pressing.
Embodiment 2: as shown in Figure 2, present embodiment extremely-low density light material laminate is formed by 7 layers of alkali-free glass fiber cloth lightweight prepreg 1 laminating hot pressing.
Embodiment 3: as shown in Figure 3, present embodiment extremely-low density light material laminate is formed by 3 layers of alkali-free glass fibre felt lightweight prepreg 1 laminating hot pressing.
Embodiment 4: as shown in Figure 4, present embodiment forms central layer by 3 layers of oxford lightweight prepreg 1 laminating hot pressing, respectively is covered with one deck alkali-free glass fiber cloth lightweight prepreg 2 and forms extremely-low density light material laminate through hot pressing the two-sided of aforementioned central layer again.
Embodiment 5: as shown in Figure 5, present embodiment forms central layer by 2 layers of alkali-free glass fibre felt lightweight prepreg 1 through laminating hot pressing, and the two-sided one deck alkali-free glass fiber cloth lightweight prepreg 2 that respectively is covered with at aforementioned central layer forms extremely-low density light material laminate through hot pressing again.
