優(yōu)點(diǎn)
通過資料我們發(fā)現(xiàn)上述產(chǎn)品具有很好的輕質(zhì)高強(qiáng)性能,在國外的QPC公司的輕質(zhì)GMT工藝如下幾種,即:Azdel 的超輕系列GMT(superLite),Symalite LWRT,較傳統(tǒng)的GMT輕質(zhì)系列產(chǎn)品,擁有血多不同的特性。SymaLITE®產(chǎn)品具有加熱中的loft 性能和模塑加工性能,產(chǎn)品的密度只有0.3g/cm3,增加了Z軸方向的挺直度。
瑞士Quardrant Plastics Composites (QPC)公司推出了一系列輕型的增強(qiáng)熱塑性復(fù)合材料(LWRT),包括片材和預(yù)制坯料,商品名為Symalite。由于LWRT復(fù)合材料密度較小,其每單位重量產(chǎn)生的硬度要比傳統(tǒng)的玻璃纖維氈增強(qiáng)熱塑性(GMT)片材高,同時(shí),這種材料與金屬、GMT以及傳統(tǒng)的PP和尼龍長纖維熱塑性(LFT)復(fù)合物相比,具有可減輕重量、設(shè)計(jì)更靈活以及成本更低的優(yōu)勢,因此使其成為輕型GMT 復(fù)合材料的理想替代品。
SymaLITE is a super-light composite sheet consisting of thermoplastic resin fiber (polypropylene) and glass filament. The base sheet is first heated to expand several times the original thickness and is then compression-molded at a low pressure. Allowing the precise control of thickness and density in various parts of the product, SymaLITE gives super-light molded products that also feature outstanding strength and rigidity. Further, SymaLITE allows diverse combinations with different surface materials.
